vent stack fire
vent stack fire
(OP)
Has anyone experienced vent stack fires at offshore platforms during thunderstorms????
My case is with around 0.5 MMscfd discharge through the vent to atmosphere- the source being mostly purge gas & leak from compressor seals.
What is the solution to prevent such fires??

The problems faced by me against the solutions-
Flame arrestor gets clogged over a period of time. Again how do we maitain the flame arrestor on a 200 feet vent stack of 8" diameter pipe??
The pressure from the compressor seals is too low & hence the same is vented to atmosphere, hence flaring is not an option.
Do we have anything else??
RE: vent stack fire
If your problem is that the gases at the vent stack ignite during a storm, you need to prevent them from getting them.
Depending what they are, you can scrub them prior to venting or maybe enev consider recompressing the gases with a vapour recovery system

RE: vent stack fire
Use a water ejector at top of vent to induce the flow of gases and the resultant intermingling of gas and water mitigates against ignition.
